The utility model discloses simple structure, the aerogenerator of adaptable difference, the range of application is extensive.
Description
Technical field
The utility model relates to detection system, is specifically related to a kind of on-line monitoring system for measuring wind-power electricity generation machine vibration.
Background technology
Wind-power electricity generation has the feature of clean environment firendly, when present more and more stricter to environmental protection requirement, day by day come into one's own.Wind-power electricity generation utilizes Wind power propelling fan blade to rotate and then drive electrical generators generating, generator shaft easily produces nuisance vibration in the process rotated, therefore need to monitor vibration, but because wind-force is general all unstable, size variation is larger, cause the changes in amplitude of generator main shaft vibration also larger, its vibration of size of blower fan specification is also different in addition, in existing vibration monitor system, there are some in order to different Vibration Conditions can be adapted to, that designs is more accurate, cause complex structure and cost is higher, and the comparatively easy detection system of design is difficult to adapt to preferably different Vibration Conditions, limit its range of application.
Utility model content
For solving the deficiencies in the prior art, it is simple that the utility model provides a kind of structure, the on-line monitoring system for measuring wind-power electricity generation machine vibration applied widely.
The utility model deal with problems adopt technical scheme be:
A kind of on-line monitoring system for measuring wind-power electricity generation machine vibration, comprise the reflexed light ring be fixed by socket on engine spindle, this reflexed light ring of one laser alignment, the reflection ray of light after reflexed light ring reflection that this laser instrument is launched is irradiated to other positions beyond laser instrument, the path of this reflection ray is provided with light barrier, one image acquisition device aims at this light barrier, and described image acquisition device is all connected with central processing unit with laser instrument, and a display is connected with this central processing unit.
As the further improvement of such scheme, described laser instrument and light barrier are all positioned at the below of reflexed light ring.
As the further improvement of such scheme, described image acquisition device is ccd video camera, and described display is liquid crystal LCD display.
The beneficial effects of the utility model: the light reflection that the utility model utilizes reflexed light ring to be sent by laser instrument is on light barrier, recycling image acquisition device gathers the position of hot spot on light barrier, if there is vibration in main shaft, the then position meeting change of hot spot, the position data of hot spot is sent on central processing unit by image acquisition device, being shown by display after central processing unit process.The utility model structure is simple, and technology maturation is easy to utilize.Main shaft less to some vibrations in addition, light barrier can be arranged from the place away from main shaft, make the corresponding increase of facula position amplitude of fluctuation, otherwise the distance of light barrier and main shaft can be reduced, by adjusting the distance of light barrier and main shaft, enable this monitoring system adapt to the aerogenerator of different vibration state, expand its range of application.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is structured flowchart of the present utility model.
Embodiment
Clear, complete description is carried out, to understand object, the characteristic sum effect of the invention fully below with reference to embodiment and the accompanying drawing technique effect to the design of innovation and creation, concrete structure and generation.Each technical characteristic in the invention, can combination of interactions under the prerequisite of not conflicting conflict.
See figures.1.and.2, a kind of on-line monitoring system for measuring wind-power electricity generation machine vibration, comprise the reflexed light ring 2 be fixed by socket on engine spindle 1, one laser instrument 3 aims at this reflexed light ring 2, the reflection ray of light after reflexed light ring 2 reflects that this laser instrument 3 is launched is irradiated to other positions beyond laser instrument 3, here the digital reflex light that is meant to can not return by original optical path, the path of this reflection ray is provided with light barrier 4, one image acquisition device 5 aims at this light barrier 4, described image acquisition device 5 is all connected with central processing unit 6 with laser instrument 3, one display 7 is connected with this central processing unit 6.
Improve further embodiment, described laser instrument 3 and light barrier 4 are all positioned at the below of reflexed light ring 2.Because aerogenerator is all be positioned at eminence, supported below by pillar, laser instrument 3 and light barrier 4 are all positioned at the below of reflexed light ring 2, make laser instrument 3 and light barrier 4 have comparatively sufficient place to install.Described image acquisition device 5 is ccd video camera in addition, and described display 7 is liquid crystal LCD display.
When the utility model is by work, central processing unit 6 controls laser instrument 3 emission of light and irradiates reflexed light ring 2, light is irradiated on light barrier 4 after reflexed light ring 2 reflects, and the position data that image acquisition device 5 gathers hot spot on light barrier 4 sends central processing unit 6 again to, shown by display 7 after central processing unit 6 pairs of data process, be convenient to observe.
The above is the utility model preferably embodiment, and it does not form the restriction to the utility model protection domain, as long as realize the purpose of this utility model with substantially identical means all should belong to protection domain of the present utility model.
